In wing chun in order to see our opponents movements coming we relie on watching the lead elbow and lead knee. When throwing a straight punch, the elbow travels at half the speed of the fist, allow us to see the punch coming. In a hook, it is even slower, up to 4times slower than the fist, allowing us to see it coming and stop it. It is basically the same principle in kicks. When your opponent throws a front kick with the lead leg, his knee travels at half the speed. In a round house, it's 4 times slower. If he kicks off the back leg, still watch the front leg because his knee will move (twist) to the movement. It takes some practice but this is a very efficient way to keep an eye on your opponent and what his intentions are.

I think this is the first post in which I haven't been quietly chuckling at your words while typing. You have finally made me lose interest as I now continue to type only for post count.

So what you are saying is you watch the first strike. Then you get KTFO with the second strike you obviously didn't visually register coming. All of that extraneous physics bs aside, its obvious you don't know that the first strike is almost always likely to be a set-up/distraction. Again, what you are preaching is ludicrous.

It took me a while to choose this, because there was just so much evidence of it. The interesting thin to note as you scout through youtube is just how many Chunner's seem able to pull off this kind of blocking, with an almost 100% success rate.
